Welcome DD. I am one of the few who believe the Enclave had more going for them than the rig and Navarro. This topic is extremely volatile.
There are even a lot of aspects that Enclave supporters can't agree upon.
For example are they legitimate gov't or a shadow government?
Did they have other bases, plans, etc?
As far as Enclave in NV, with main Enclave operations in FO2 more in the northern realm of California, it isn't surprising that there are only old remnants in the Mojave region. Enclave in California would no doubt be underground, as they would be hunted by NCR. But, they would have had time to prepare. It would have been years after FO2 before the NCR had a army to engage the Enclave.
In terms of Enclave gear, well, it would be nice to get our hands on some nice tech. Enclave combat armor, pulse rifles and pistols, gauss weapons, new PA and other energy weapons would all be fun stuff to play with.
